Abstract(in English) | The authors have developed stepped multiple frequency CPC, which is a proprietary modulation/demodulation method that can realize high range-resolution with narrow reception bandwidth. When extending stepped multiple frequency CPC to the bandwidth of 4GHz, it is necessary to make the frequency steps unequally spaced in order to maintain the conventional observation time. However, this raises the problem that the range-ambiguity increases. In this paper, we mitigate the range-ambiguity by CS and evaluate its mitigation performance. From statistical evaluation by simulation, when SN is 4dB and false alarm rate is ?10?^(-7), the detection rate of DFT (conventional method) is about 0.07, whereas the detection rate of CS is about 0.83. |
